I think you are on the right track, this reminds me of something I learned from AbrahamHicks...Basically they state that it is beneficial to focus on the task at hand.
I believe they say something like "focus in a life giving way in every moment"
Thinking about things is okay but I think the goal for me will be to use that thinking time to visualize how I want my future to be...so while I am working or eating, or reading or working out, or taking a bath or meditating or doing my hair I will be a focused being...when I am bored or standing in line or driving I will try to visualize and manifest
I hope this makes sense
